I say focus on getting an education or some type of trade knowledge, if you aren't college minded.
Next, keep your credit right! Don't create a lot of debt, if you can help it.
Regarding relationships, dating, etc..Don't settle down! Play the field and date a wide variety of women.
Learn what you like, don't like, etc. You will have plenty of time to settle down when the time is right.
In all, OP, live life! Get a passport and travel, if you have the means to do so.
Lastly, do not get caught up in trying to live up to other people's expectations as well as societal standards.
Everyone has his or her own path, so do you while finding your way through life. When you do decide to settle down with a career and possibly start a family, then start saving toward your retirement.
The sooner you do that, the better off you will be when the time comes for you to retire.
